SPECIFICATION forming part of Letters Patent No. 288,901, dated November20, 1883.

: Application filed July 24,1883. (No model.)

To all whom it may concern.-

Be it known that I, NATHANIEL T. Wnrn ING, of San Francisco, in thecounty of San Francisco and State of California, have invented a new anduseful Improvement in Elevated ater-Tanks, of which the following is afull, clear, and exact description, reference being had to the annexeddrawing, forming part of this specification.

Thisinvention relates to elevated tanks for filling street-sprinklingwagons with water; and the invention consists of the construct-ionhereinafter described and claimed.

The drawing is a side elevation of atank and sprinkling-wagon, theformer being partly broken away, and showing 'my invention.

A is a tank resting on suitable supports, B B. The tank is to he made ofwood or iron, and entirely closed, with the exception of the vent-pipeM, and is to he made of sufficient strength to resist the pressure inthe watermain under the street, from which it is supplied with waterthrough the pipe 0.

N is a check or flap valve secured to the roof of the tank, in positionfor closing the vent-pipe M automatically by the rising of the water inthe tank through the pipe 0. The

under side of the valve is made convex, in orand described.

der that when the tank is full it may be embeddedin the water and heldfirmly closed to prevent overflow. The convex under side, however, maybe omitted, if desired. As an outlet for-the water, I provide a metallicpipe, 0, arranged in the bottom of the tank, and provided with a cock,P, and leverQ, or with a wheel and screw-valve for opening and closingthe pipe. A short hose, F, communicating with the water-receptacle 0nthe sprinkling-wagon E, is to be attached to the lower end of pipe 0 forfilling the receptacle from the tank.

D is an air-chamber on top of the tank, to prevent the entire exclusionof air from the tank when the latter is filled with water.

lVhat I claim is The elevated water-tank having the inletpipe (3, thevent-pipe M, and convex checkvalve N, adapted to close said pipe M, theairchainber D, and the outlet -pipe 0, having cock P and lever Q,substantially as shown NATHANIEL TRUMAN WIIITIXG.
